ffmpeg exited with status

Error message

ffmpeg exited with status %d

What it means

The ffmpeg subprocess exited non-zero during video muxing. Guard: capture ffmpeg stderr, include it in the error, and clean up partial output files on failure.

Solutions

1. Run the same ffmpeg command manually to see the full error output.
2. Verify ffmpeg is installed and supports the requested codecs/formats.
3. Check input files, disk space, and permissions used by the mux step.
